Operationalizing a model to quantify implementation of a multi-component intervention in a stepped-wedge trial

The delivery and receipt and each of the components that constitute these are measured on a scale between 0 and 100, with 100 being the optimal delivery and is therefore expressed in percentage
*The value is identic to the value of the total intervention, though there are no specific values for each intervention component
